Permaprint Premium - water-based screen printing ink - 100% solvent free.
PERMAPRINT PREMIUM is a water-based screen printing inks with superior performance. This ink are formulated for printing on paper coated and uncoated, cardboard, tyvek, glass (not scratch resistant), polyesters, polycarbonates (lexan), some coated metals, polystyrene and wood. Care should be taken with some vinyls as plasticizer migration may soften the ink over time. Care should also be taken with some uncoated papers as cockling may occur.
Permaprint Premium is suitable for use on high lay-down hand printed wallpaper and art reproduction, through to stickers, pacakaging, posters and more. Permaprint Premium ink totally eliminates the use of solvents so it's not only safe for the environment and the printer, but ensures equipment can be easily cleaned up with water and solvent fumes are eliminated.
Screen meshes of 32-120T (83-305 tpi) monofilament polyester are suitable for most PermaPrint Premium applications. Ensure adequate ink on the screen for even print. Between prints, ensure ink is flooded over entire image area to prevent drying-in. Ensure that screen emulsions and blockout are water-resistant and fully cured.
Mesh: PermaPrint Premium is used commercially with mesh counts from 32T metric (83 tpi) for high lay down hand printed wallpaper and art reproduction to 120T (305 tpi) on applications such as stickers, posters where maximum detail and transparency is required. General purpose work is best with mesh from 77-100T (195-255 tpi). Polyester mesh is preferred over nylon.
Squeegee: Sharp square urethane squeegees from 55° shore to 75° shore hardness are recommended.
Stencil: Water resistant stencils are essential with PermaPrint Premium.
Drying: PermaPrint Premium dries by simple evaporation over 20-30 minutes or can be jet dried at 65-75°C (149-167°F) for approximately 30-45 seconds. With porous substrates, drying is aided by absorption. Drying rates are affected by ink thickness. Testing under print shop conditions on substrates is recommended before commencing.
